It’s not unexpected that a Vault Dweller may choose to shed or cover their Vault Suit after spending time above ground, but one identifier stays with them no matter what: the Pip-Boy. This wrist-worn computer device does a ton of helpful things from reporting the wearer’s health and stats, to mapping their travels, to playing the radio, and even giving them access to other Vaults. Wastelanders will automatically ping you as a Vault-Dweller when they see you rocking this iconic accessory.
